Comparing Enphase IQ8 to IQ7 Capacity
Compared to the Enphase IQ7, the IQ8 enables your solar system to generate power during an outage (kit required). Furthermore, if you are adding an Enphase battery now or in the future, you may want to consider the IQ8 series because they offer more scaling flexibility to your backup capacity. IQ8 microinverters can also match the power output of highly efficient panels, especially those panels that are larger than 60 cells, such as 66-cell, 72-cell, and 84-cell solar panels.
When choosing between the different IQ8 models (IQ8, IQ8+, IQ8M, IQ8A, IQ8H), it is generally smart to choose a microinverter that will generate slightly less power than the maximum power your panels can produce. This is because factors like shading often cause panels to produce below their maximum power output. For most home projects, IQ8M and IQ8+ are sufficient.
